Wash 5 thin wall sample tubes at once. Take up solvent directly from a bulk container for extended solvent capacity. The sturdy construction of the washer and the 1000ml heavy-wall vacuum flask add durability, while the PTFE, PFA, and Pyrex components make the system inert to most solvents. A special 3-way valve allows for evacuation of the chamber, washing and air drying with just a turn of the handle. Some assembly of components is required (no tools are needed). Furnished complete as shown, less sample tubes. Full details are available upon request
